Let a thousand string concatenations bloom

How many different ways (in PHP) are there to concatenate the string values in two variables and put the result in a third variable?



Here are a few to start:

• $alice = $bob . $charlie;
• $alice = "$bob$charlie";
• $alice = sprintf('%s%s', $bob, $charlie);
• ob_start(); echo $bob, $charlie; $alice = ob_get_clean();
• $alice = implode('', array($bob,$charlie));

I would say something like “Of course, this entire exercise is just for fun and in practice is totally useless,” but whenever I start out thinking that something actually productive eventually emerges. So perhaps this is totally useless, perhaps not!
